What is biogas?

Diagram of biogas plant

The batch of slurry, silage, corn or other feedstock, as well as
agricultural and livestock waste, after being ground and sometimes subjected to
a hygienization process or pasteurization, is directed to special hermetically
sealed fermentation tanks.

Biogas (biomethane) is produced by a natural biological process, a result of the
anaerobic fermentation process that occurs with the participation of bacteria. After
appropriate treatment it is combusted, driving the cogeneration unit which in
turn produces electricity and heat. Ecological organic fertilizer, free of
unpleasant odors and harmful microorganisms, is produced as a by-product. The
whole process of preparing the batches for the manufacture of products in the
form of electricity, heat and organic fertilizer is monitored electronically.

Agricultural biogas plants could accurately be called "concrete cows"
because the whole process of biogas production is almost identical to the
digestive processes occurring in the body of a cow.
